You should at least read the thread on my Duster build. I've been working on mine for 2 years now and it will probably be another 6 months before it is running. I've tried a bunch of different things in my build and have changed course a few times. I started off with a motor plate but then decided to go with a spool mount setup. There is no perfect solution, each approach has some good and bad. You have to figure out what the goal is before you'll get very far. If you want a simple bracket racer that is easy to work on then that is different than a hard core race car which is a lot different than a street car. If you know what you're building then it is possible to get the project finished. If you aren't sure what you're building then you'll either never finish or never start.
